"Eatented July 31, 1906;

Application filed March i9, 190e. serial No. 306,804..

To all whom it may concern: g

Beit known that I, SYLvEsTER WARNER, a citizen ofthe United States, anda resident of West Union, in the county of Parke and State of Indiana,have invented a new and Improved Land-Roller, of which the following isa full, clear, and exact description.

The purpose of the invention is to provide a roller especially adaptedfor rolling listed corn, being capable of operating upon two or morelisted ridges.V

A further purpose of the invention is to provide rollers especiallyadapted to the shape of the ridges and which will not only roll the topor crown of a ridge, but will also crush the earth at the side edges,where it is most needed.

Another purpose of the invention is to .construct the rollers with anouter section independent of the body-section and slidable thereon, sothat said outer sections by their movement upon the main sections willaccommodate themselves to variations in the width of the ridges and alsoto provide tensioncontrolled regulating devices for the outer sectionsof the rollers which will overcome their tendency to crowd outward tocompel ythem to act upon the edges of the ridges over which they pass.

Another purpose of the invention is to provide means for regulating theaction of the controlling device upon the outer sections of the rollers,so that any needed tension can be obtained and so that the same pressuremay be secured at all times on the outer sections ofthe rollers, thuspreventing them climbing up upon the ridges when they reach their Widefaces.

A further purpose of the invention is to provide simple and convenientmeans for y adjusting the rollers bodily upon their supports toaccommodate them to diiferentsized furrows made by different-sizedlisters.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, formin a part ofthis specification, in which simi ar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improved roller, a part of the framebeing brokenaway. Fig. 2 is a vertical longitudinal section taken on theline 2 2 of Fig. 1. Fig. 3 is a rear elevation of the improved roller.Fig. 4 is a horizontal section taken through a portion of the frame anda sectional plan vi ew of one of the tension-equalizing members, drawnupon an enlarged scale. Fig..5 is a transverse section takensubstantially on .the line 5 5 o f Fig. 1 and drawn also upon anenlarged scale, and Fig. 6 is an enlarged transverse ection takensubstantially .on the line 6 6 of represents the frame of the machinesaid frame being of skeleton construction, comprising a front beam 10, aparallel rear beam 1 1, and end beams 12, together witha centraltransverse beam 13, to which latter beam the pole 14 is secured, fittedwith any suitable draft device A. A shaft 1.5 extends from end to end ofthe frame, being passed through the `central beam 13, and this shaft isheld stationary in the frame in any .approved manner-for example, bypassing .a cotter-pin 16 through .one `of its ends or through both ofits ends and the frame, if required.

B represents the rollers, which are mounted to turn on the shaft '15.These rollers are of spool shape, and each consists of a cylindricalbody-section 17,"an inner conical headsection 18, secured to or integralwith the body-section, and an outer conical opposing head-section 19,which outer sections 19 are free to slide to a limited extent on thebodysections 17 of the rollers, .as is shown best in Fig. 2. These outerhead-sections 1.9 are preferably provided with apertures 20, so as torender them more or less light, and are yfurther provided at their hubor central portions each with a sleeve 21, and these sleeves .areloosely mounted on the fixed shaft 15 andextend into chambers 22produced in the outer end portions of the body-sections 17 of therollers, as is 4also shown in Fig. 2. By thus constructing the rollers Bthey are enabled to accommodate themselves automatically to variationsinthe widths of the ridges, andthe peculiar shape of the rollers enablesthem when traveling over ridges to crush earth at IOO the sides of theridges as well as at the top or l crown of the ridges.

The fixed shaft 15 is provided with series of apertures 23 at each sideof its center, and these apertures receive pins 24, which have bearingagainst washers 25, located between them and the opposing inner endportions of the rollers, so that by changing the position of the pins onthe shaft 15 the rollersB may IOS IIO

' tral portion of the frame.

be made to lie more or less closely to the cen- Sleeves 26 are looselymounted on the end portions of the fixed shaft 15, and these sleeves 26engage with the outer end portions of the sliding outer end sections 19of the rollers, and in connection with these outer end sections 19combined regulating and tensioning mechanisms C r are employed, appliedthrough the medium of levers 27, the said levers being pivoted at theirforward ends in the forward corner portions of the frames by' pins 28 ortheir equivalents, and the rear ends of the said levers extend outthrough slots or openings 30 in corresponding portions of the rearmember 11 of the frame, as is shown in Figs. 1 and 3, and each of thelevers 27 is provided with an elongated opening 29 between its ends,through which openings the shaft 15 passes.

The regulating and tensioning mechanism C is as follows: An opening 31is made in the rear member 11 of the frame lat each side of the centerof said member, as is shown in Fig. 3, and a pivot bolt or pin 32 ispassed vertically through each of said openings 31. A peripherally-`rooved pulley 33 is eccentrically and loose ymounted on the said pin,as is 4 best shown in Fig. 4, and a smaller periphr also best shown inFig. 4.

erally-grooved pulley 34 is attached to or formed integral with theupper face of each eccentric pulley 33. The smaller pulleys areconcentric with relation to the bolts 32, as is Chains 35 are secured tothe periphery of the eccentric pulleys 33, and these chains 35 arecarried outward and are secured to the outer rear ends of the levers 27by means of suitable eyes 36 or their equivalents. Chains 37 areattached to the periphery of the concentric pulleys 34, winding thereonin a contrary direction to the winding of the chains on the eccentricpulleys. The chains 37 from the concentric pulleys 34 are carried towardthe center of the said rear member 1 1 of the frame and are attached toa post 38, mounted to turn in brackets 39, extending out from the topand bottom portions of the said rear member 11 of the frame, as shown inFigs. 3 and 5. This post 38 is provided with a polygonal head 40, sothat it can be readily turned with a wrench 0r like tool, and at itsupper portion, above the upper bracket 39, a disk 41 is secured to ormade integral with the post, said disk having any desired number ofapertures 42 therein, through which apertures a pin 43 is passed intothe frame to hold the post in the position in which it may be set, andeach chain 37 between its ends is provided with a spring 44 of anydesired construction, as shown in Figs. 1 and 3 and in this manner thesliding end sections of the rollers are free to move outward, but arenormally crowded inward, so that they will act at all times on theridges over which they may pass and accommodate themselves to variationsin the width of the ridges, and at the same time a uniform tension isexerted in an inward direction upon the said outer sections of therollers, which tension may be increased or decreased at will, and thisspring tension prevents the rollers from creeping up on the ridges.

A suitable seat 46 is located at the rear of the machine, supported by aspring-standard 45, attached usually to the central beam 13 of theframe.
